Introduction. Dacryocystorhinostomy (DCR) is the «gold standard» of surgical treatment for the obstruction of tear ducts complicated by dacryocystitis. Whichever access is used for the dacryocystorhinostomy, it remains a traumatic and painful operation that requires a long-term postoperative recovery. New methods of DCR are designed to reduce the negative aspects of this intervention without sacrificing the success rates for both the external and endonasal techniques of the operation. Coblation is a controlled process in which radio-frequency energy is supplied to the conducting medium, causing a focused plasma field to form around the electrode. The plasma field consists of highly ionized particles with sufficient energy to break the organic molecular bonds within the tissue. Aim. To study the initial results of coblation dacryocystorhinostomy. Material and methods. We performed 46 unilateral endonasal dacryocystorhinostomies with the use of cold plasma equipment (Coblator II machine with 5874-01 EIC electrode). The results of the operations were evaluated after 1, 3 and 6 months. We analyzed the complaints of the patients and conducted endoscopy examinations of the nasal cavity to view the results of the dacryocystectomy. We also conducted a light probe and irrigation of the lacrimal ducts. Results. Use of the cold-plasma ablation method during endonasal endoscopic dacryocystorhinostomy simplifies the operation: it eliminates the use of forceps, nibblers, sickle blade, rasp and radio knife. As a result of the minimal damaging effects on the tissues surrounding the ablation zone, and the absence of their charring and extensive necrosis, epithelization of the bone opening is faster, with less risk of scarring and granulation. Conclusion. The efficiency of endonasal DCR using cold plasma was 93.5%. It is less traumatic, less prolonged, and with minimal bleeding. Coblation is also appropriate when restoring a previously created, but healed-over tear pathway.
